The 6021W subminiature tube have a fairly long lifetime (20000 hours). Assuming you leave it on 24 hours 365 day =8760 h, the tubes will last for 2.5 years. At that point you there is no warranty left and you (or a friend) can safely solder new ones into the player yourself. If the player is still under waranty you might want to sent it back to the distributor. In the worst case shipping it to the US distributor and back should not be more than $150 roundtrip, which is still less than what most people spent on tube rolling in three years.
Also one more comment: I have had pretty good experience with the Audio Aero distributor (Globe Audio). I got my Prima as a DEMO from the dealer with a slightly dented cover. Globe Audio send me a new replacement directly from Canada to the US, no shipping charges. Also, they always answered my questions with great detail and promptly. Nice to have someone standing behind the products they sell, which is particularly important with overseas products.
Happy listening.
